General:
The SCR-23 L-band PSR is an unattended Air Route Surveillance Radar with high reliability. Its detection range is beyond 420km for civil and military aircrafts below the height of 18000m.

Parameters

Technical Features:

l  Advanced system: high repetition frequency for blind filling, frequency diversity, selectable linear / circular 

         polarization and independent weather channel to realize strong target detection in complex environment.

l  Stable software platform: Linux OS, highly-stable software to support the customizing requirement.

l  Precise processing: flexible parameters during signal processing, plot processing and track processing, and 

          parameter adjustment with practical situation to optimize the radar performance.

l  Strong anti-jamming capability: various anti-interference methods including low side lobe antenna, large 

dynamic range receiver, anti-asynchronous interference, anti-saturation interference, anti-second trip 

echo, CFAR, original echo processing, plot filter and special section processing.

l  High reliable mode: fail-soft system and seamless switch design to ensure fully automatic recording and reporting

         for 24h continuous operation.

l  Rich test performance: with the rich fault detection and test system, accurate location, fault diagnosis and clearstatist    ical 

         report forms, it can provide the real-time report of plot, track, data quality and radar performance.
